Heh, my turtles get a smorgasboard. Grapes, melons, kale, collared greens, spinach, broccoli (rarely), chopped carrots, whatevers seasonally available out of my garden, fish, worms, turtle diets.
I'll try to get him to take pinkies; he's so tiny, not too much bigger than a baby corn snake. I guess I can just scent a thawed pinky with fish?
